The results of a series lowest-order constrained variational calculations for various nucleon fluids are presented. based upon the Reid soft-core potential (1968) and allow in self-consistent fashion explicit excitation into an N*(1234) state via recent transition proposed by Green, Niskanen Sainio (1978). For nuclear matter binding energy 16 MeV per is obtained at saturation density 0.25 N fm-3. compressibility calculated to be 300 MeV. From study asymmetric symmetry coefficient 33...

With the recent rise in popularity of wearable personal health monitoring devices, a number concerns regarding user privacy are raised, specifically with regard to how providers these devices make use data obtained from and protections that enjoys. waterproof monitors intended be worn 24 hours per day, companion smartphone applications able offer analysis sharing activity data, we investigate compare policies four services, extent which services protect privacy, as find do not fall within...

Recently, Internet of Things (IoT) deployments have shown their potential for aiding the realisation Sustainable Development Goals (SDGs). Concerns regarding how IoT can specifically drive SDGs 6, 11 and 9 in developing countries been raised with respect to challenges deploying licensed unlicensed low-power wide area network (LPWAN) technologies opportunities consumers service providers. With infrastructure protocols being ubiquitous each proposed different SDGs, we review compare various...

A novel approach to handover management for Long-Term Evolution (LTE) femtocells is presented. Within LTE, the use of self-organizing networks (SONs) included as standard, and one its cases. Base stations can autonomously decide whether should take place assign values relevant parameters. Due limited range femtocells, requires more delicate attention in an indoor scenario allow efficient seamless from outdoor macrocells. As a result complexity radio environment, frequent ping-pong handovers...

Modern smart phones are now capable of gathering information about a user's social interactions. The authors have developed and deployed Nodobo, suite sensor software for Android. Our first study group is class senior high school students, each using Google Nexus One mobile phone running which we use to capture their device usage patterns We provide an overview the system architecture, describe trial, share some initial results.

The article describes a statistically multiplexed radio access mechanism for third-generation mobile systems, which is an integral part of resource allocation functional entity. key feature the RACE Mobile R2084 Advanced Time Division Multiple Access (ATDMA) project. It presents indication design parameters adopted this and performance characteristics derived from comprehensive computer simulation model. gives particular emphasis to structure module illustrates how integrated with...

In many areas of the world accessing professional physicians "when needed/as needed" might not be always possible for a variety reasons. Therefore, in such cases, targeted e-Health solution to safeguard patient long-term health could meaningful approach. Today's modern healthcare technologies, often built around electronic and computer-based equipment, require an access reliable electricity supply. Many technologies products also presume high speed internet is available, making them...

Following the suggestion by Brown, we have considered a model of nucleus 18O in which, addition to usual shell-model picture two neutrons coupled an inert 16O core, also included collective deformed state represented two-proton excitation but axially symmetric potential. For given interaction (the Kallio-Kolltveit interaction), four fitted parameters oscillator constant, effective charge and single-particle spectrum) variational deformation parameters) managed reproduce lowest eight known...

This paper presents a top-down designer-driven design flow for creating hardware that exploits partial run-time reconfiguration. Computer-aided (CAD) tools are presented, which complement conventional FPGA environments to enable the specification, simulation (both functional and timing), synthesis, automatic placement routing, configuration generation control of partially reconfigurable designs. Collectively these constitute dynamic circuit switching CAD framework. A Viterbi decoder is...

Purpose – The purpose of this paper is to examine the influence European countries in Region 1 Radio Sector International Telecommunications Union (ITU-R). More specifically, focus on World Radiocommunication Conference 2012 meeting explore whether decline. Design/methodology/approach This article adopts in-depth case study 700-MHz issue. Qualitative data are drawn from semi-structured interviews with key stakeholders who participated at meeting. Findings concludes that ITU-R has changed....

The Internet of Things (IoT)-the connection small smart sensors, actuators, and other devices to the Internet-is a key concept within home. To ease deployment, such are often wireless battery powered. An important issue is interface used. ubiquity Wi-Fi in homes today makes this an attractive option, but relatively high power requirements conflict with requirement for long life low maintenance. Lower alternatives, as Bluetooth ZigBee, have been proposed, these much smaller installed base. In...

This paper examines the railway environment from point of view provision 2nd generation voice services. It radio including fading, Doppler, transients, and penetration loss into carriages, as well special situations such cuttings tunnels. The reports on operation IS-95 GSM services at high speeds, both assuming track side base stations non-track stations. draws conclusions different types encountered for conventional speed rail lines, effect these factors have overall link budget.

The Galitskii-Feynman $T$ matrix, which sums the ladder diagrams for both particle-particle and hole-hole scattering in a many-fermion system, is shown to have singularity at negative values of c.m. energy interacting pair. appears as first-order pole position function density system total momentum pair, corresponds formation bound pairs medium. structure exists two distinct Fermi systems (liquid ${\mathrm{He}}^{3}$ nuclear matter), detailed numerical results are presented using potential...

Abstract A mobile ad hoc network (MANET) is a self‐organized wireless where nodes can communicate with each other without the use of any existing infrastructure or centralized administration. Trust establishment and management are essential for security framework MANETs. However, traditional solutions to key through accessing trusted authorities servers infeasible MANETs due absence infrastructure, frequent mobility, link instability. In this paper, we propose robust self‐organized, public...

Fast-acting, yet cost-effective, communications is critical for smarter grid monitoring, protection, and control. This paper demonstrates a new approach the real-time compression of Sampled Value (SV) data based on IEC 61869-9 recommendations. applies simple rules, yields excellent performance — typically compressing to less than half original size. leads significant beneficial reduction in encoding time (in merging unit producing SV data) decoding (at end application), as well main benefit...

This paper proposes a market-based framework in which service providers, network operators and users are able to trade communications services. For this purpose, middleware has been specified software agents can supply or purchase QoS contracts. Benefits from the proposal increased competition provision of mobile services, an integrated for management services networks multi-provider environment possibility develop smarter applications that make efficient use scarce radio spectrum.
